ou. nnnnnn,

. e. citizen of the United States, residing at lll titl

Sen Francisco, in the county of Sen Frein cisco and State of California, have invented o new end useful .improvement in Uil'Burnm ers, of which the following is o s i iec,iii :e-

tion. ,l

'll/,ly invention relates to improvements in oil burners, in which n rotating cup mounted on suitable bearings, driven et high speed by the ineens 01"' air, steam, or other gases; distributes on the inside of the cup e thin film of oil which is mixed with air, steam, or other after leaving the cup, et which time it is ignited and burns;` the ob ject ot my invention is toprovide o burner which een be mounted. either horizontally or vertically and one that will swing in amd out in either position with the barrel or nozzle traveling opproiimetely parallel with the airisoyf the opening in' the lire-box and one thot'ivill automatically shut oil the'oil when the burner is Withdrawn; in so doing)i dispensing with ell flexible pipes now use` to oon/inet the fuel oil to 'the burner; also to provide e. 'wey for lubricating theball bearings by means of e combined reservoirl und separator.

Referring to 'the accompanying drawings which illustrate the invention, l e side elevation of the burner partly broken sway, showingr the burner in forward or iring position; Fig. o roer elevation. showing upper oil joint in section; Fig. 3 is s, side elevition showing burner withdrawn from tiring position; Fig. fi is an enlarged View of upperA oil joint showing the shutoil position of thejoint; Fig. 5 is 'on enlerged view of the ball bearing mounting sli-owingf the oilreservoir and treed tube leading 'to the reservoir,

Similar numerals Afreier to similar ports throughout the several views. The costing; l, 'with thread 8, for oir, stream or oonneotiom and thread 9, for oil connection comprises the bese 'for the burner; to this is elemped air, steam or link "il, and oil elbow-- l0, by ineens of strop 3, Land bolts 5 and 6, held by nuts 7, und kept properly spaced by spacing-sleeves fl. Adjustment for weer is teken core oit by ineens of screws ll and l2, which oreloelred in place by nuts 13 and le. Air, steam er gas linlr 2, lies butterlly relire lo, mounted on n 31% 1921. Serial No. 483,201.

and. held by screw 17 g friction to hold valve in place is through spring 20, which is held in place by' Washer 18, end pin 19.l The upper IendV ot air, steam or gas link 2, is hinged tothe elbow 21, by-'screw pins 22L and 23, and is looked in plae by Wing nut 24. To oil-elbonT 10, is screwed pipe 25, `which with oil joint 26 sindv 27, forms the oil link. 'Oil joints 26 and 2T, are held together byu thread on the end of 27 g the nut 29, screws against Washer 30; the Washer 30, and nutl 29, turning With2?. When in firing position hole, in 26, registers with liole 33,

in piece 27, allowing the oil to pass through;

when Withdrawn the holes 33 and 34, do not register so no oil can pass to the burner; screw 28, is for cleaning purposes. The

hollow stationary shaft 32, passes through.

elbow 2l, and is locked in position by nut 31, and'is screwed into piece 27; this construction Aallows elbow 2l, to travel in a line parallel hto the axis of the hole in the lirebox hy the swinging notion of links 2, und 2F.

To the inside end of 32, is fastened e ball bearing container 39, which is supported on the outside by perforated plete 4:0. lnside this container 1s mounted on ball bearings 43end 51, a hollow shaft 44C, on 'the end of `which is` fastened, etomizing cup 49, and driving wheel 53, which has numerous angular outs or 'venes on the outer surface; The bearings are held on to the Shaft by nut 50,

'f screwing Aagainst the inside `race of 51, clamping the inside roce of 43, egainst thev shoulder of 44, by ineens of separator 41 the outer race oft 5l, is clamped agoinstfa. shoulder 54 by the oil reservoir 'and separetor 52, which in turn is held by the out/er race o' 43, which is held'bylloclmut 15; loclinut 45, is prevented from Working loose hy screw (t6. The reservoir 52, receives its oil through pipe 38, and hole 3'?, in handle handle 36, has oil cup 35.', screwed into the top. Nozzle t8, is screwed to the elbow 2l, end incloses cup 4:9, and bell bearing container 39; tube 47, leeds fuel oil to cup.

To operi-ite, .Wingnut 2l, is loosened and burner rocked forward to position as in when Wingnut 24, is tightened, holding burner in place. To Withdraw burner loosenv Wingnut 24C, and pull boel: o'n handle `36; burner will then tekelthe position es in F153. 3., shutting or?. "the fuel oil' through the notion o holes $3 ond 34;, 27

es. It will be observed that the una com nections 2 and 25 are. illustrated in the drawings as broken and it is preferred that these members be of such length as to provide an I equal distancev betweenA the pivot points 9 and 33, and 8 and 22, whereby the burner in its movement topor from active firing position has im rted thereto a substantially straight line o movement. 10 The invention claimed 1s:

1. In combination with an oil burner including a support, a. tubular bumer body,

` pipes pivotally mounte thereto, said pivotal connections being disposed in a plane substantially in alignment w'ith the lon itudinal alzis1 oi tiie burner, szflid 1 rov-1 1` ripara e 11n mounting or gaisbiirner axbrding a meanswhereby the burner when moved into and from active firing osit'ion is maintained in a substantially orizontal position.`

2. An oil burner including a base, a burner supported thereby and including a fluid -pressure Vactuated rotatable burner cup, ay

uid channel within the burner and leadino to the cup, a pair of pipes pivotally mounted at their ends one in advance of the Lemaire other ,on said base and at their discharge ends pivotalll f connecting one in advance of i the other Wit Suid burner, one for supplying air the hunner and the other for supplying uei to the charmed, said pipes affording a pivoted link support for the burner.

3. An oil burner including a tubular burner body, means for supplying oil and ai? thereto, said means including a pair of pipes pivotully connected one Ain advance of the other at one end to the burner and at their opposite. ends to asupport, one pipe affordine' an air supply7 and the other an oil supplj, said pipes affording an oscillating,r frame support for the burner whereby the burner is maintained. in a. substantially hori zontul path in its movement to or from active firing position.l

4. An oil burner including a tubular burner body, means for supplying oil and air thereto, said means `including a pair of pipes pivotally connected one in advance of the other at one end to the burner and at their opposite ends to a support, one pipe affording an nir supply und the other an oil supply, Suid pipes affording a link su port for the burner whereby a substantially straight. line movement is imparted to the burner in its movement to or from lactive firing position.
